The end of the block. Tracks paralleling closer as we ran. Each time just enough advance, the whistle preceding, jumpup bolting out the door. Pennies, nickles, carefully placed during the rumbling advance of steel. Vaguely menacing in its forcefull momentum. Do they mind? Pounded 5 minutes flat, cars rolling, colors and rust melding. Burlington northern green and white. Searching between ties rocks and rails, warm metal discs, flattened thin. The process more important than the result, treasured and lost shortly after.
